▎ 摘　　要

NOVELTY - Preparing luminescent composite system of photoresist-reduced carbon quantum dots, comprises carrying out solvent dispersion of carbon quantum dots and further dispersing in ionic liquid, mixing with photoresist, and carrying out in-situ reduction by ultraviolet curing to obtain final product. USE - The luminescent composite system is useful in electroluminescent electronic device (electroluminescent light-emitting diode devices), photodetectors, display applications, bioimaging, biosensing and drug delivery (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for luminescent composite system of photoresist-reduced carbon quantum dots prepared by above method.
